NEW MAC Address Prefix for Polycom Voice Products

Hello all,


Polycom is coming to the end of MAC prefix 00:04:F2:xx:xx:xx after nearly 16 million plus devices built.

There is a new MAC prefix, 64:16:7F:xx:xx:xx, which will be used on devices going forward.


The products involved are all Voice products, including all Desktop and Conference phones


Customers need to add the new MAC prefix 64:16:7F:xx:xx:xx, which may result in having to modify existing administrative scripts and/or applications to identify devices belonging to either MAC range, as Polycom voice products.
